In his 12th season at the helm of the Boulder festival, Christie — whose contract has been extended to 2017 — has lined up an inventive progression of orchestral and chamber music, world music, jazz and family programs through Aug. 3.

First up was pianist Simone Dinnerstein, opening the festival on June 24 with an elegant, deeply-felt interpretation of Beethoven’s Piano Concerto No. 2 in B-flat Major, Op. 19.

That said, the nuanced musical minims that distinguish her exceptional construal of Bach’s Goldberg Variations and Partitas were largely absent in her delivery of the concerto’s decidedly Romantic-era temperament.
